Analysis of Lichen Metabolites, a Variety of Approaches

“…11.1. Some dedicated NMR studies related to several structural families were published: depsides (Cheng et al 2013), tridepsides (Narui et al 1998), depsidones and depsones Huneck 1980, 1981), xanthones (Sundholm 1978(Sundholm , 1979, and triterpenes (Wenkert et al 1978;Wilkins et al 1990). A compilation of the published NMR data of lichen compounds is reported in the Huneck and Yoshimura (1996).…”
